Answer:
so from looking at this we can see there is
0=5
1=5
2=3
3=2
4=4
5=1
6=2
7=2
8=1
9=1
now we have to add them up
5+6+16+5+12+14+8+9=75
and now we have to add up the total plots on the chart
5+5+3+2+4+1+2+2+1+1=26
now we divide
75 divided by 26=2.88461538462
so 2.9 is the mean
now we add up the number from least to greatest
0,0,0,0,0,1,1,1,1,1,2,2,2,4,4,4,4,5,6,6,7,7,8,9
so the medien is 4
Hope This Helps!!!
Step-by-step explanation:
Finding the median
The median is the number that is located in the middle of the set of numbers. First you count the number of X's, which is 26. This means that the median is in between number 13 and 14, which is 2 and 3 in this number set. Then you average the two numbers ([tex]\frac{2+3}{2}[/tex]) to get 2.5.
Finding the mean
The mean is the average of all of the numbers located in the set. First, you add up all of the numbers.
5(0) + 5(1) +3(2) + 2(3) +4(4) + 1(5) + 2(6) + 2(7) + 1(8) + 1(9) = 81
After, you divide by how many numbers there are in the set, which as we found earlier, is 26
[tex]\frac{81}{26}[/tex] = 3.12

Decrease 1500goats by 20%
A 1200
B 300
C 1800
D 900
Answer:
A
Step-by-step explanation:
1500 goats represent 100%
but 100% = 5*20%
1500 = 5*300 so 20% =300
a decrease by 20% is 1500-300 = 1200
Una empresa textil dedicada a la confección y venta de pantis Glamour realiza la siguiente promoción de sus productos: para pedidos de hasta una decena, el par de pantis Glamour de cualquier tamaño lo vende a S/. 5. Pero si se hacen pedidos mayores a una decena de pares, cada par de media tiene un valor de S/. 3.
Respuesta:
S / 25
S / 45
S / 75
Explicación paso a paso:
Dado :
Para pedidos de hasta una docena; par de pantimedias Glamour Costo S / 5
Para pedidos de más de una docena; par de pantimedias Glamour Costo S / 3
Función de costo:
Para x ≤ 12
Costo, C = 5x
Para x> 12
Costo, C = 3x

Write the equation of the line that goes through points (0, 4) and (6, 16).
Answer:
y = 2x + 4
Step-by-step explanation:
(x₁ , y₁) --> (0 ,4) & (x₂ , y₂) = (6 , 16)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{16-4}{6-0}\\\\=\frac{12}{6}\\\\m = 2[/tex]
(x₁ , y₁) --> (0 ,4)
y - y₁ = m(x - x₁)
y - 4 = 2(x - 0)
y - 4 = 2x
y = 2x + 4
This graph shows how the length of time a kayak is rented is related to the
rental cost. What is the rate of change shown in the graph?
Kayak Rental
A. 8 hours/dollar
B. 4 hours/dollar
C. $4/hour
D. $8/hour
Answer:
option D.
Step-by-step explanation:
[tex]rate \: of \: change \: = \frac{change \: in \: y}{change \: in \: x} [/tex]
let's take any point on the graph. let's say (2, 16)
and one point we know is (0, 0)
[tex]rate \: of \: change = \frac{16 - 0}{2 - 0} [/tex]
= 16($) / 2 (hrs)
= 8 $/ hrs
that is option D.
Answer:
$8/hour
Step-by-step explanation:
Hi there!
In this scenario, the independent variable is time and the dependent variable is the cost. The cost of renting the kayak depends on how much time passes. Knowing this, the answer should be formatted like _ dollars/hour, not _hours/dollar. We can rule the first two options out.
Now, looking at the graph, when 1 hour passes, the cost is $8. This occurs at point (1,8). And this is constant throughout, for example, when 2 hours pass, the cost is $16 (2,16).
Therefore, the rate of change shown in the graph is $8/hour.
I hope this helps!

Answer:
3) x = 55, y = 123, z = 123
4) x = 276°
Step-by-step explanation:
3)Angles P and Q are alternate interior angles, so are congruent.
P = Q
3x -42° = 2x +13°
x = 55° . . . . . . . . . . . add 42°-2x
Then Q = 2x +13 = 2(55°) +13° = 123°.
Angles Y, P, Q, and Z are all congruent, so all have the same measure.
Y = Z = 123°
__
4)If you draw a horizontal line parallel to AB and CD through point O, then small angle POQ is divided into parts that are congruent with angles APO and CQO. That is, small angle POQ = 48° +36° = 84°.
Large angle POQ is then 360° -84° = 276°

Answer:
Just did this problem! Hope it helps
The proofing that ABCD is a parallelogram is done using parallelogram side theorem.
What is parallelogram side theorem?parallelogram side theorem simply means that the opposite sides of a parallelogram are equal and also parallel to each other.
As, ABCD is a parallelogram.
So, BAC and DCA are alternate interior angles.
Also, AB||CD and BC||DA.
then, BCA and DAC, are alternate interior angle.
Now In ABC and CDA
BAC= DCA (proved above)
BCA= DAC (proved above)
AC= AC (Common)
By ASA congruency criteria,
ΔABC≅ ΔCDA
Hence, AB= CD and BC= DA (cpctc)

A manufacturer receives a shipment of 100 parts from a vendor. The shipment will be unacceptable if more than five of the parts are defective. The manufacturer is going to randomly select K parts from the shipment for inspection, and the shipment will be accepted if no defective parts are found in the sample. How large does K have to be to ensure that the probability that the manufacturer accepts an unacceptable shipment is less than 0.1? Hint: We recommend using R to plug in different values of K.
A. 42
B. 22
C. 32
D. 12
Answer:
C. 32
Step-by-step explanation:
The shipment for 100 parts is received by a manufacturer. Shipment will be rejected if more than 5 parts are defective. The manufacturer selects a sample and based on that selected sample he accepts or rejects the whole shipment. The minimum size of the sample should be 32 based on the probability of less than 0.1 and then decision should be made whether to accept or reject the shipment. If no defective part is found in the sample, shipment should be accepted.

a rectangular field is 5x meters long and 2x m wide. if its perimeter is 140cm what is its area?
Answer:
1000 cm²
Step-by-step explanation:
perimeter = 2 * length + 2 * width
2 * 5x + 2 * 2x = 140
10x + 4x = 140
14x = 140
x = 10
Length: 5x = 5(10) = 50
Width: 2x = 2(10) = 20
area = length * width
area = 50 cm * 20 cm
area = 1000 cm²
